Maxwell's Fourth Equation expresses the observation that a continuous electrical current I or a displacement current (∂D/∂t) gives rise to a magnetic field. At a distance r from a wire with direct current I, for example, the magnetic field is given by (4.20G)H=2Icr (4.20S)H=I2...
What is a solid angle in physics? Find the angle of refraction for a ray of light that enters a flint glass from the air at an angle of 30.0^o to the normal. The critical angle for an air-glass interface is 29.6^o. When a light ray in air is incident on the interface, the...

The gravity equation allows one to conclude that: Force and masse are directly proportional (the larger the mass, the larger the force). Force and distance are inversely proportional (the longer the distance, the weaker the force). When the concept of mass is approached in physics, it is im...
to DE behavior. We match the parametrization with current data, and deduce that the adiabatic and effective sound speeds of DE play an important role in inferring the cosmological parameters. We find that there is a preferred transition redshift of1+z≃29−30, and some reduction in the ...
We are thus asked to find P1. Solution Solving Bernoulli’s principle for P1 yields P1=P2+12ρv22−12ρv12=P2+12ρ(v22−v12)P1=P2+12ρv22−12ρv12=P2+12ρ(v22−v12) Substituting known values, P1=71.01×105 N/m2+12(103 kg/m3)[(25.5 m/s)2−(1.96 m/s)2]=4.24...
On the other face of the medal, with respect to accurate PES, we find simple model potentials. Their usage is very instructive for qualitative studies like the investigation of the impact on the dynamics of the topology of the PES around a conical intersection or the understanding of the key...
To find the secondary field, we have to use the solution of Laplace’s equation that decreases as the distance from the ellipsoid increases. Let us assume that the second type of solution has the form (3.124)Us(ξ,η,ς)=BG1(ξ)F2(η)F3(ς). This presentation is very natural ...
We establish a mapping between the moments of the field u(r) at a distance r from a point on the absorber, and the partition functions of certain star polymers. The scaling with r of each moment is governed by an independent exponent λ(n), which we calculate to order (=4-d). Non...
